CVE-2026-95375 is an improper access control vulnerability in Chromium WebView tag APIs exposed to the chrome-untrusted://lens WebUI context. A compromised Lens renderer could create a WebView guest, invoke loadDataWithBaseUrl with attacker-controlled content and an arbitrary valid HTTP or HTTPS base URL, and cause the guest document to receive that supplied origin. The attacker could then invoke executeScript, whose authorization check allowed execution, to run JavaScript in the spoofed-origin guest. Chromium corrected the issue by prohibiting loadDataWithBaseUrl, executeScript, addContentScripts, insertCSS, and captureVisibleRegion for WebView instances embedded by chrome-untrusted contexts.
